iOS Infuse Pro v3.4.1 and Kingston mobilelite G2 wireless

Attempting to use the Infuse Pro app on iPhone and iPad Air with SMB connection to stream movies from Kingston mobilelite G2 wireless device but consistently receiving “An error occurred loading this content” when playing back movie . The error occurs most times before the movie starts or a minute or two into the movie. Trying to play MP4 and AVI files which play fine with Infuse on black Apple TV. Getting frustrated, need help! Movies play fine when streamed from NAS over home WiFi.
